Overall I read that the size of a single layer wii iso image is 4 699 979 776 bytes == 0x118240000 == 143432 blocks (block size=32768). This value is also supported by libwbfs.

But a little analyze of my about 60 discs tells me, that the maximum is only 4.684.775.424 bytes == 0x1173c0000 == 142968 blocks. This value is taken from the end of the data partition. 52 discs have exact this values and the others are smaller. Only the one double layer is greater.

Been a while since I had to paste in this:
* If the file is 4,699,979,776 bytes, it is unscrambled.
* If the file is 4,700,012,544 bytes, it was unscrambled with unscrambler 0.4 (unscrambler adds 32,768 bytes to the file).
* If the file is 4,736,698,368 bytes, it is a raw file and must be unscrambled.

Dual layer had not appeared yet.

As it pertains to your question I guess it is halfway between "correct" for some and a standard based on early dumping methods- a bit like how roms are not trimmed.
